No listener listening on port 50000 after restart Netweaver CE 7.2

[Former Member]

I installed Netweaver CE 7.2 MaxDB on Solaris 10 x64 then deployed ACC on it.

It used to work well until after a restart, there is no listener listening on port 50000.

The url is http://<IP>:50000/, which is not responding.

Because a java component hung, I called "stopsap j2ee" then "startsap j2ee".

But I found there is no listener on port 50000. Then I called "stopsap all", reboot the local zone where sap runs on, "startsap all".

I noticed there is "Unable to open trace file sapstartsrv.log." but don't know if this is the cause. I can not find anything related in SAP notes.

I found on Linux x86_64 that there was no x_server executable in the /sapdb/clients/<SID>/bin path. There was one in the /sapdb/programs/bin path.

I changed the startj2eedb script in /sapmnt/<SID>/exe/uc/linuxx86_64/ path to use the x_server executable in /sapdb/programs/bin/. I found I had to

change the sticky bits for user and group with chmod us and gs for the x_server file (to be the same as the sdbggloballistener executable.

NB: I don't know if this is a valid workaround, but I was desperate!

Cheers!

I found that the reason is sapdb is not started successfully. I tried to start the db but it failed. Can anyone help solve this problem and start the database? [Sorry about the format. There is no way to fix it]
